Asked to post anonymously. You Can’t Tell Me What To Do You’re Not My Grandchild Shirt! Today after school at the school playground of a private school in Yorba Linda (cannot post name of school for privacy reasons) I saw a grandfather picking up his grandson from school. They were standing by the playground. He wanted to play for little while with some of his friends. Immediately the grandfather went into a rage. Started grabbing the boy tightly by his forearm. For a moment he calmed down, but that was short lived.
